Definitions

  • the invention relates to an extractable support device comprising a drawer housing provided with a handle having two arms each mounted for rotation about an axis and together occupying a first position in which they extend substantially parallel to one face of the drawer housing. and a second position in which they extend substantially perpendicular to said face of the drawer housing, the drawer housing being intended to be inserted in a sheath housing.
  • Such a device is intended primarily to be installed in a vehicle, electronic equipment such as a radiotelephone transmitter / receiver being embedded in the drawer housing. It allows rapid assembly of electronic equipment in the vehicle and disassembly if necessary by simply removing the drawer housing from the sleeve housing.
  • the drawer housing is generally equipped with an electrical connector arranged to be forced into a complementary electrical connector provided on the sheath housing permanently fixed in the vehicle.
  • the extraction of the drawer box from the sheath box is done by exerting a pulling force on the handle, the arms of the handle then occupying the second position. It is necessary to exert a significant pulling force so that the electrical connectors separate from one another, knowing that in the case of a radiotelephone transmitter / receiver, the electrical connection pins are numerous (generally 21 points). In addition, the pulling force exerted by a user on the handle is generally much greater than that required to separate the electrical connectors, which causes over time damage to the electrical connectors and the handle.
  • Patent document DE-B-1,209,626 discloses an extractable support device of the above type, in which each arm of the handle has a free end arranged to bear against the sheath case when said arm is moved between its first position and its second position so as to move the drawer housing relative to the sheath housing by a cam effect.
  • the separation of the electrical connectors is then no longer done by a pull on the handle in the direction of insertion of the drawer housing in the sheath housing, but by a cam effect due to the rotation of the arms of the handle around their axis of rotation.
  • the user can easily control the force necessary to exert on the handle to separate the electrical connectors. Since the handle is no longer subjected to excessive force, it can be made lighter.
  • the electrical connectors are locked in the insertion position by the effect of frictional forces on the electrical connection pins of the electrical connectors.
  • the disadvantage of such a locking means is that it quickly leads to the deterioration of the electrical connection pins when the drawer housing is often removed from the sheath housing.
  • the mentioned patent document provides a means for locking in the insertion position the electrical connectors comprising a lock secured to the sheath housing and resiliently biased in a notch provided on the drawer housing.
  • this lock is arranged on the front face and actuated by hand, directly.
  • the invention aims to overcome this drawback.
  • the lock is arranged on the rear face and, to facilitate the extraction of the drawer housing from the sheath housing, there is an unlocking means for releasing the lock from the notch .
  • a sliding plate inside the sheath housing is provided to rotate said latch around its axis so as to release it out of the notch, this plate being disposed inside the housing sheath so as to slide under the effect of a pushing force exerted by the free end of an arm of the handle when the latter is moved between its first position and its second position.
  • the unlocking of the electrical connectors and the extraction of the drawer box from the sheath box are obtained by a single action on the handle thanks to a stop integral with the sheath box which is designed to limit the movement in translation of the plate relative to the sheath box .
  • a spring is provided to act against the translational movement of the plate relative to the sheath housing.
  • the drawer box leaves the sheath box under the action of the spring against the plate.
  • the user can therefore visually check that the drawer box is correctly inserted into the sheath box.
  • the spring exerts a pushing force on the drawer housing via the plate, which causes the drawer housing to be ejected from the sheath housing.
  • the plate under the action of the spring, forces the arm to occupy the second position by a cam effect.
  • the front face of the drawer housing therefore remains clear when the drawer housing is completely inserted in the sheath housing.
  • Figure 1 is a side view of the drawer housing.
  • Figure 2 is a side view in longitudinal section of the sheath housing.
  • FIGs 3 to 7 illustrate different positions of the drawer housing of Figure 1 in the sheath housing of Figure 2.
  • the extractable support device comprises on the one hand a drawer housing visible in FIG. 1 and a sheath housing visible in FIG. 2.
  • the drawer housing comes to be inserted in the sheath housing.
  • the drawer housing 1 has a substantially parallelepiped shape having front, rear, side, upper and lower sides.
  • a U-shaped handle 12 having two arms 15 each mounted for rotation about an axis 16 secured on a lateral side.
  • the two arms can move between a so-called folded position which they occupy when they extend substantially parallel to the front side 17 of the drawer housing and a so-called deployed position which they occupy when they extend substantially perpendicular to said front side. of the drawer housing.
  • the drawer housing is also provided on its rear side with an electrical connector 13 with pins for example.
  • a notch 14 is formed on the upper sides of the drawer housing at the rear thereof by molding or the like.
  • the arm 15 visible in FIG. 1 has a free end 18 which extends over a length L beyond the axis 15. This free end serves as a lever arm to extract the drawer unit from the sheath unit. It is understood that the two arms 15 have the same characteristics.
  • the sheath housing 2 also has a parallelepiped shape having front, rear, side, upper and lower sides.
  • the front side 20 of the housing 2 is open.
  • the drawer box is therefore inserted into the sheath box by its front side as indicated by the arrow F.
  • sheath housing When the sheath housing is embedded in the console of a vehicle, its front side 20 is substantially in the same plane as the panel 3 of the vehicle console.
  • the sheath housing is provided on its rear side with an electrical connector 23 complementary to the electrical connector 13.
  • Each lateral side of the sleeve housing carries at the rear, an L-shaped lock 24 rotatably mounted on an axis 25.
  • the lock moves in rotation in a plane parallel to a lateral side of the sleeve housing.
  • the L branch of each lock is intended to be introduced into the notch 14 of the drawer housing when the latter is completely inserted in the sheath housing, the connectors 13 and 23 also being inserted one inside the other.
  • Each axis 25 of a lock carries a coil spring 26, one end of which is pressed against the trunk of the L of the spring and the other end is left free.
  • a plate 28 is slidably mounted on a slide for example.
  • each plate 28 is disposed between a lateral side of the drawer housing and the same lateral side of the sheath housing.
  • Each plate 28 extends substantially between the axis 25 of a lock and the front side of the sheath housing.
  • the end of the L of the bolt bears against a ramp 29 formed on the rear face of the plate 28.
  • the free end of the spring 26 also bears on the rear face of the plate 28 and exerts a force thrust on the latter indicated by the arrow P. Consequently, the end of the L of the bolt is permanently pressed against the ramp of the plate 28 under the action of the spring 26.
  • Two stops 22, 21, for each plate 28 are provided on the lower side of the sheath housing to limit the translational movement of the plate. These two stops are distant by a distance less than the distance L so that the travel of the plate 28 is also less than the distance L.
  • the plate 28 at rest, comes to bear on the stop 21 under the effect of the pushing force exerted by the spring 26 on its rear end. In this position, the plate 28 maintains the trunk of the spring substantially parallel to the upper side of the sheath housing.
  • the ramp 29 of the plate lifts the branch of the L of the lock by the pivoting effect of the latter around its axis 25. Furthermore, the rear end of the plate 28 compresses the spring 26. The movement of the plate 28 is limited by the stop 22.
  • the drawer housing 1 is partly introduced into the sheath housing 2.
  • the arms 15 of the handle occupy a folded position.
  • the plates 28 are in abutment against the stops 21.
  • the latches 24 are in abutment against the ramps 29 of the plates 28.
  • the drawer unit 1 is further advanced in the sheath unit in the direction indicated by the arrow F. It has its rear side which then comes into contact with the branch of the L of the latches 24 which has the effect of making them rotate about their axis 25 as indicated by the arrow a.
  • the spring 26 is compressed.
  • the drawer housing is completely inserted in the sheath housing.
  • the electrical connectors 13 and 23 are inserted one inside the other.
  • the latches 24 pivot around their axis 25 as indicated by the arrow b.
  • the branches of the L of the locks 24 are therefore stressed elastically in the notch 14 of the drawer housing by the springs 26.
  • the electrical connectors 13, 23 are then locked in the insertion position.
  • the arms 15 of the handle are rotated around their respective axis 16. They are moved by an angle A1 from their folded position to occupy an intermediate position.
  • the free ends 18 of the arms push the plates 28 which slide from front to rear of the sheath housing.
  • the plates 28 are now in abutment against the stops 22.
  • the plates 28 have released the latches 24 out of the notch 14 by pivoting them as indicated by the arrow c.
  • the arms 15 are maneuvered in rotation about their axis 16 to now occupy their deployed position.
  • the free ends 18 of the arms push on the front end of the plates 28 which are in abutment against the stops 22.
  • This has the effect of moving the drawer housing relative to the sheath housing and therefore to separate the electrical connectors 13,23.
  • the free ends of the springs 26 push on the rear ends of the plates 28, which has the effect of ejecting the drawer housing out of the sheath housing.
  • the latches 24 pivot around their axis as indicated by the arrow d. The plates 28 then come to bear against the stops 21.
